Average Calculator - Mean, Median, Mode, Range & Standard Deviation
Calculate arithmetic mean, median, mode, geometric/harmonic mean, sample & population standard deviation, variance, and IQR instantly. 100% private.
This calculator processes all descriptive statistics, central tendency measures (arithmetic mean, median, mode), and dispersion metrics (sample/population variance, standard deviation, IQR, and MAD) 100% locally in your browser memory. Results are provided for academic research, engineering benchmarks, and educational exploration. For sample variance, Bessel’s correction (n - 1) is automatically applied to guarantee unbiased population parameter estimation.
Zero-Knowledge Local Execution
All mathematical computations execute strictly inside your local browser memory. Zero external server uploads.
Sub-Millisecond AST Engine
Instant real-time reactive computation delivers immediate feedback on every keystroke with zero network latency.
Production Standards & Compliance
Strict adherence to official specifications, ensuring enterprise accuracy and zero data leaks.
